Developing theory-based risk-reduction interventions for HIV-positive young people with haemophilia

HAEMOPHILIA, Issue 1 2001
J. R. Schultz
Eleven haemophilia treatment centres in the United States collaborated in the Hemophilia Behavioural Intervention Evaluation Projects (HBIEP) to develop theory-based interventions to reduce the risk of HIV transmission from seropositive adolescents and young adults with haemophilia. While the Transtheoretical Model of Behaviour Change and the Theory of Reasoned Action provided the theoretical underpinnings, the exact form in which these theories would be applied depended on developmental research. This paper presents the various phases of the process to develop the theory based interventions: literature review, qualitative interviews, quantitative surveys, a provider survey, a materials review, and the actual planning. All or portions of this process could be applied to the development of interventions for many behaviour-change projects. A description of the HBIEP interventions is also provided. [source]


Impact of therapeutic advances on hypoglycaemia in type 2 diabetes

DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 4 2008
Patrick J. Boyle
Abstract Patients with type 2 diabetes experience hypoglycaemia less frequently than those with type 1 diabetes. Some protection against hypoglycaemia is afforded by the relatively intact glucose counter-regulatory pathways that characterize the pathophysiology of early type 2 diabetes. To some extent, this protection explains why hypoglycaemic episodes in intensively treated individuals with type 2 diabetes, when they occur, are rarely severe. As diabetes progresses and therapy intensifies to achieve recommended glycaemic goals, hypoglycaemia frequency and severity increase. Thus, when it comes to instituting intensive therapy, fear of hypoglycaemia may contribute to health-care providers' ,clinical inertia'. Because maintaining glycaemic control is so important to both public and individual health, many new therapies and technologies have been developed. This manuscript reviews and considers whether these advancements in therapy make glycaemic goals easier to achieve by minimizing hypoglycaemia. Putting the hypoglycaemia experienced by type 2 diabetes patients into appropriate clinical perspective, the impact of recent progress made in pharmacotherapy, drug delivery systems, and BG monitoring on hypoglycaemia incidence is largely positive. The extent to which this progress can effect improvement over traditional therapies will, however, depend upon patient (and provider) education, motivation and behaviour change.

Physical activity consultation for people with Type 2 diabetes.

DIABETIC MEDICINE, Issue 8 2007
Evidence, guidelines
Abstract Physical activity is an important, but often underused, therapeutic strategy within diabetes care. To date, little is known about the best way to promote physical activity in diabetes care. Physical activity consultation is an intervention designed to promote physical activity behaviour change. This article provides guidelines on how to conduct a physical activity consultation with people who have Type 2 diabetes, and reviews the evidence surrounding the effectiveness of this intervention in this population. The trans-theoretical model is the underlying theory of behaviour change for the physical activity consultation intervention. The review identifies research which supports the use of this model for understanding physical activity behaviour in people with Type 2 diabetes. The review outlines a number of modifiable variables associated with physical activity behaviour change in this population. How each of these variables is addressed within the guidelines for conducting a physical activity consultation is identified. Finally, limited but consistent research highlights the effectiveness of physical activity consultation for promoting physical activity in people with Type 2 diabetes. [source]

A match,mismatch test of a stage model of behaviour change in tobacco smoking

ADDICTION, Issue 7 2006
Arie Dijkstra
ABSTRACT Aims An innovation offered by stage models of behaviour change is that of stage-matched interventions. Match,mismatch studies are the primary test of this idea but also the primary test of the validity of stage models. This study aimed at conducting such a test among tobacco smokers using the Social Cognitive Stage Model. Design A match,mismatch field-experiment was conducted in which smokers and ex-smokers in different stages were assigned randomly to one of three information conditions. Participants Smokers in the pre-contemplation stage, the contemplation stage and the preparation stage, and ex-smokers in the action stage (n = 481), who were recruited through mass media, were assigned randomly to one of three information conditions. Intervention In each of the three information conditions, participants received a four- to six-page computer-tailored letter designed to: (1) increase the positive outcome expectations of quitting, (2) decrease the negative outcome expectations of quitting or (3) increase self-efficacy. Measurements Forward stage transition was the primary outcome measure, which was assessed 2 months after the participants received the information. Findings At the 2-month follow-up, the matched interventions were significantly more effective in stimulating forward stage transition (44.7%) than were mismatched interventions (25.8%; odds ratio = 2.78; confidence interval = 1.85,4.35). Conclusion The present study provides experimental support for the benefits of stage-matching and for the validity of the Social Cognitive Stage Model. [source]

ADDICTION, Issue 11 2005
Abu Saleh M. Abdullah
ABSTRACT Objective To examine whether telephone counselling based on the stages of change component of Transtheoretical model of behaviour change together with educational materials could help non-motivated smoking parents of young children to cease. Design Randomised controlled trial. Setting Hong Kong Special Administrative Region, PR China. Participants 952 smoker fathers and mothers of Chinese children aged 5 years. Intervention Participants were randomly allocated into two groups: the intervention group received printed self-help materials and three-session telephone-based smoking cessation counselling delivered by trained counsellors; the control group received printed self-help materials only. A structured questionnaire was used for data collection at baseline and at 1, 3 and 6 month follow up. Main outcome measures The main outcome is 7 day point prevalence quit rate at 6 months (defined as not smoking during the 7 days preceding the 6 month follow up) determined by self reports. Other secondary outcomes were self reported 24 h point prevalence quit rate and self-reported continuous quit rate and bio-chemically validated quit rate at 6 months. Results A total of 952 smoker fathers and mothers were randomized to the intervention (n = 467) and control (n = 485) groups. Most were daily smokers (92.4%) and the mean number of cigarettes smoked per day was 14.5 (SD = 8.9). By using intention-to-treat analysis, the 7 day point prevalence quit rate at 6 month follow up was significantly greater in the intervention group (15.3%; 68/444) than the control group (7.4%; 34/459) (P < 0.001). The absolute risk reduction was 7.9% (95% confidence interval: 3.78% to 12.01%). The number needed to treat to get one additional smoker to quit was 13 (95% CI: 8,26). The crude odds ratio of quitting was 2.3(95% CI: 1.5,3.5). The adjusted odds ratio was 2.1 (95% CI: 1.4,3.4) (adjusted for age, number of years smoked, and alcohol dependency). Conclusion Proactive telephone counselling is an effective aid to promote smoking cessation among parents of young children. [source]


When smokers are resistant to change: experimental analysis of the effect of patient resistance on practitioner behaviour

ADDICTION, Issue 8 2005
Nick Francis
ABSTRACT Aims In the field of motivational interviewing, practitioner confrontational behaviour has been associated with lower levels of patient behaviour change. We set out to explore whether resistance to change among smokers affects practitioner confrontational and other behaviours. Design Experimental manipulation of levels of patient resistance in a role play. Setting The study was conducted at the start of a 2-day health behaviour change workshop. Participants Thirty-two practitioners who had registered for the workshop. Intervention The practitioners were assigned randomly to interview a standardized patient (actor) who portrayed a smoker who had been briefed to display either high or low levels of resistance to change. Measurements Interviews were audiotaped and transcribed. Practitioners and standardized patients completed interview ratings at the end of each interview. After listening to each taped interview practitioners were assigned a global score for confrontation, empathy and expert instructional style. Interviews were then submitted to a qualitative analysis. Findings Higher levels of practitioner confrontational behaviour were observed in the high resistance group. This was evident both from the global scores (median 2 versus 0, P = 0.001) and the qualitative analysis. Global scores for empathy and expert instruction were not significantly different. Qualitative analysis also suggests a pervasive negative impact on other practitioner behaviours. Conclusions Higher patient resistance probably leads to an increase in confrontational and other negative behaviours in health professionals attempting to promote behaviour change. This challenges important assumptions about the influence of practitioner behaviour on patient behaviour and subsequent health-related outcomes. [source]


Return to work following unilateral enucleation in 34 horses (2000,2008)

EQUINE VETERINARY JOURNAL, Issue 2 2010
M. E. UTTER
Summary Reasons for study: The effect of unilateral enucleation on vision and potential loss of performance in horses has received little study. Objective: To evaluate the likelihood of return to prior discipline following unilateral enucleation in horses, assessing the role of age at enucleation, equine discipline, reason for enucleation, time to vision loss and eye enucleated. Hypothesis: Unilateral enucleation has no significant effect on likelihood of return to work in horses, for both right and left eyes, across age and discipline. Method: A retrospective review of medical records identified 92 horses that underwent unilateral enucleation at the University of Pennsylvania New Bolton Center from April 2000,April 2008. Case variables determined from the medical record included breed and sex of horse, age at enucleation, which eye was enucleated, reason for enucleation and onset of vision loss. Pre- and post operative occupations were determined by telephone interview with the owner or trainer of each horse. Results: Based on hospital surgery logs, 92 enucleations were performed over the 8 year period and 77 records were available for review, with follow-up information available for 34 horses. Of these, 29/34 (85%) horses returned to work in pleasure or trail riding (11/13), flat racing (7/10), hunter/jumpers (4/4), dressage (3/3), group lessons (1/1), eventing (1/1), steeplechase (1/1) and as a broodmare (1/1). Four of 5 horses (4/34, or 12% sample) that did not return to work (2 pleasure and 2 racing) were retired due to anticipated or perceived decrease in performance or behaviour change following unilateral enucleation, with the remaining horse retired from racing for lameness issues unrelated to enucleation. Twenty-two of 25 horses (88%) with acute vision loss and 7/9 horses (78%) with gradual vision loss returned to their previous discipline. Conclusions: Horses are able to return to a variety of occupations after unilateral enucleation. [source]


Ontogeny of Acoustic and Feeding Behaviour in the Grey Gurnard, Eutrigla gurnardus

ETHOLOGY, Issue 3 2005
M. Clara P. Amorim
Although sound production in teleost fish is often associated with territorial behaviour, little is known of fish acoustic behaviour in other agonistic contexts such as competitive feeding and how it changes during ontogeny. The grey gurnard, Eutrigla gurnardus, frequently emits knock and grunt sounds during competitive feeding and seems to adopt both contest and scramble tactics under defensible resource conditions. Here we examine, for the first time, the effect of fish size on sound production and agonistic behaviour during competitive feeding. We have made sound (alone) and video (synchronized image and sound) recordings of grey gurnards during competitive feeding interactions. Experimental fish ranged from small juveniles to large adults and were grouped in four size classes: 10,15, 15,20, 25,30 and 30,40 cm in total length. We show that, in this species, both sound production and feeding behaviour change with fish size. Sound production rate decreased in larger fish. Sound duration, pulse duration and the number of pulses increased whereas the peak frequency decreased with fish size, in both sound types (knocks and grunts). Interaction rate and the frequency of agonistic behaviour decreased with increasing fish size during competitive feeding sessions. The proportion of feeding interactions accompanied by sound production was similar in all size classes. However, the proportion of interactions accompanied by knocks (less aggressive sounds) and by grunts (more aggressive) increased and decreased with fish size, respectively. Taken together, these results suggest that smaller grey gurnards compete for food by contest tactics whereas larger specimens predominantly scramble for food, probably because body size gives an advantage in locating, capturing and handling prey. We further suggest that sounds emitted during feeding may potentially give information on the motivation and ability of the individual to compete for food resources. [source]


Effects of routine education on people newly diagnosed with type 2 diabetes

EUROPEAN DIABETES NURSING, Issue 3 2009
A Clarke SRN, PhD Health Promotion & Research Manager
Abstract Background: In Ireland, there is limited knowledge about the perceptions or behaviours of people newly diagnosed with diabetes and, due to the lack of a national register, poor knowledge of their demographic profile. Aim: To add to the body of knowledge about diabetes, to obtain perceptions of people newly diagnosed with type 2 diabetes who attend group diabetes education, and to examine their relationships with the adoption of diabetes self-management behaviours. Method: A correlational study was conducted among people attending routine group diabetes education at three diabetes clinics during 2006/7, from which a convenience sample of 168 (38%) participants were recruited. Results: Men newly diagnosed with diabetes were younger, waited less time to attend group diabetes education, had a more positive diabetes attitude and perceived themselves to have more social support than women. Women had better diabetes self-management dietary and medication adherence behaviours prior to attending group diabetes education than the men. Conclusion: People newly diagnosed with diabetes differ in their attitude, perceived support and self-efficacy to adopt dietary and exercise behaviours and have different behaviour change needs at diagnosis. Post-attendance at diabetes education, they adopt behaviours at variable rates and may not sustain the change. The study findings indicate that healthcare professionals should monitor continually the need for behavioural change, in particular physical exercise behaviours in women and dietary and medication adherence in men. They should also continuously assess the maintenance of diabetes self-management behaviours of all people with diabetes, while promoting confidence in achieving desired outcomes.

Employee perceptions and their influence on training effectiveness

HUMAN RESOURCE MANAGEMENT JOURNAL, Issue 1 2003
Amalia Santos
Studies of the benefits of human resource development (HRD) for organisations have assumed a direct connection between training strategy and a hierarchy of performance outcomes: learning, behavioural change and performance improvement. The influence of workplace practices and employees' experiences on training effectiveness has received little attention. This study investigates evaluation strategies designed to elicit greater training effectiveness, and explores the influence of trainees' perceptions and work environment factors on this. Drawing on detailed case study findings, the authors highlight the importance of management practices, trainees' perceptions of the work environment and systems of reward in explaining behaviour change after training.

Using fear appeals to promote cancer screening,are we scaring the wrong people?

INTERNATIONAL JOURNAL OF NONPROFIT & VOLUNTARY SECTOR MARKETING, Issue 2 2006
Sandra C. Jones
There is debate regarding the use of fear appeals (emphasizing severe threats to health) in social marketing, to encourage preventive behaviours, such as screening for breast cancer. While it has been found that fear appeals may result in attitude and behaviour change there is also the risk of inciting inappropriate levels of fear, motivating the wrong audience or instigating maladaptive behaviour in the target group such as denial or defensive avoidance. This study examined the impact of an experimental threat manipulation for mammography screening on a group of women in regional Australia. The study found that varying the level of threat had no impact on stated intentions of the women to undergo mammographic screening. However, it also found that high-threat messages resulted in stronger negative emotional reactions and greater perceived susceptibility among younger women who are not the target group for screening in Australia. The results of this study emphasize the importance of limiting the use of high levels of threat in social marketing campaigns, and ensuring that campaigns are appropriately designed to specifically impact upon and motivate the target group.

An integrative literature review of lifestyle interventions for the prevention of type II diabetes mellitus

JOURNAL OF CLINICAL NURSING, Issue 17 2008
Suzanne G Madden
Aims and objectives., An integrative literature review was undertaken to determine what type II diabetes prevention programmes have been evaluated, what type of programme is the most effective and how adherent to lifestyle changes adults are after participating in a prevention programme. Background., Type II diabetes is important because the disease is affecting millions of people worldwide. Obesity and sedentary lifestyles are preventable risk factors for type II diabetes, leading many researchers from around the world to examine different programmes that are focussed on prevention of the disease. Design., Integrative literature review. Method., Search of electronic databases. Results., Diet, exercise, counselling and diet plus exercise were the types of prevention programmes, with the diet plus exercise being the most efficacious. Although many studies demonstrated excellent results initially, maintaining the effects of the lifestyle behaviour change proved to be difficult for participants, with only one study demonstrating the persistence of results after six years. Conclusion., Future research should focus on long-term maintenance programmes, rather than just short-term prevention programmes to determine the need for booster interventions or other means to ultimately decrease the incidence of type II diabetes. Relevance to clinical practice., As front-line healthcare providers working across a broad array of settings, nurses are particularly well-suited to play an integral part in future applications of diabetes prevention programmes. Lifestyle interventions are being delivered in a variety of settings and venues such as the workplace, the Internet and places of worship. In addition, at-risk populations also can be targeted, particularly overweight and obese persons, with at least one parent having type II diabetes or persons with gestational diabetes. [source]


An interactive education session and follow-up support as a strategy to improve clinicians' goal-writing skills: a randomized controlled trial

JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 1 2010
Elisabeth Marsland BAppSc(OT)Hons
Abstract Background, Recent research indicates that allied health clinicians have difficulty articulating client needs and priorities into specific and measurable goals. As a result, a number of strategies to facilitate improvement in allied health clinicians' goal-setting skills have been recommended in the literature. In order to assist clinicians develop the skills required to set SMART goals, it is necessary that the strategies are rigorously tested. Aim, To determine if a 50-minute education session and 3-month email and telephone support programme improves clinicians' SMART goal-writing skill and accurately predicts improved goal-writing behaviour. Methods, Concealed random allocation of participants (n = 120) into two parallel groups: (1) intervention group received education on writing goals using the SMART Goal Evaluation Method as part of a workshop on outcome measurement and received 3 months of follow-up support (n = 60); and (2) control group attended a workshop on evidence-based practice (n = 60). Results, Education and follow-up support improved clinicians' SMART goal-writing skills at both the 3- and 6-month review (Yates ,2 = 4.324, d.f. = 1, P = 0.0375). Structural equation modelling revealed education and follow-up support is an accurate predictor of SMART goal-setting behaviour change at both 3 months (standardized regression weights = 0.21; P = 0.014) and 6 months (standardized regression weights = 0.19; P = 0.02) post intervention. Changes were modest and developed over a 6-month period. Conclusion, This study provides empirical evidence that a programme of educating clinicians in a standardized method of goal setting and providing follow-up support improves allied health clinicians' SMART goal-writing skills.

Applying a ,stages of change' model to enhance a traditional evaluation of a research transfer course

JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 4 2003
Leslie L. Buckley MD MPH
Abstract The aim of this study was to utilize an evaluation tool based on Prochaska's model of change in order to assess behaviour change as part of an evaluation process for a research transfer training programme (RTTP). The RTTP was a training programme offered to scientists in a psychiatry department and research institute to gain skills in research transfer. In addition to a traditional course evaluation framework evaluating overall satisfaction with the course and whether or not learning objectives were met, an additional ,stages of change' evaluation tool designed to assess change along a continuum was utilized. This instrument measured change in participants' attitudes, intentions and actions with respect to research transfer practice and consisted of a 12-question survey completed by participants prior to taking the course and 3 months post-course. In two out of the three categories, attitudes and intention to practice, there was positive change from pre- to post-course (P < 0.05). Although there was a trend of increased RT-related action, this was less robust and did not reach significance. For the RTTP transfer course, a ,stages of change' model of evaluation provided an enhanced understanding by showing changes in participants that would otherwise have been overlooked if only changes in RT behaviour were measured. Additionally, evaluating along a change continuum specifically identifies areas for improvement in future courses. The instrument developed for this study could also be used as a pre-course, participant needs assessment to tailor a course to the change needs of participants. Finally, this ,stages of change' approach provides insight into where barriers to change may exist for research transfer action. [source]


Communication skills for behaviour change in dietetic consultations

JOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 6 2009
K. Whitehead
Abstract Background:, Both the UK's National Health Service (NHS) and the National Institute of health and Clinical Excellence (NICE) have recommended increased training for health professionals in communication skills. There is evidence to suggest that communication skills are important in helping people to change health-related behaviour, which is a key role for dietitians. This study investigated the views of UK dietitians about their training needs and experience in relation to communication skills in dietetic practice. Methods:, In October 2007, a cross-sectional survey was mailed to all British Dietetic Association members (n = 6013). The survey gathered quantitative data and free-text comments to ascertain the level, type and effect of communication skills training received by dietitians at both the pre- and post-registration level. Results:, There were 1158 respondents; a response rate of 19.3%. Ninety-eight percent (n = 1117) rated communication skills as either very or extremely important in client consultations. Post-registration training had been undertaken by 73% (n = 904). Of these, over 90% of respondents perceived that post-registration training had led to improvements in their relationships with patients, their confidence in client interviews and their ability to cope with challenging clients. However, 248 (21.4%) felt time keeping in interviews had worsened. Lack of time for client interviews was also the most commonly identified barrier (19%, n = 216) to implementing the skills. Conclusions:, This study has explored an important and under-researched area. Respondents strongly endorsed the importance of good communication skills and the benefits of post-registration training in this area. Some felt that good communication was time consuming but others felt that time management had improved. Further research and training is required to support the implementation of these skills into dietetic practice. [source]


Identifying facilitators and barriers to physical activity for adults with Down syndrome

JOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 9 2010
J. Mahy
Abstract Background Adults with Down syndrome are typically sedentary, and many do not participate in the recommended levels of physical activity per week. The aim of this study was to identify the facilitators and barriers to physical activity for this group. Method Semi-structured interviews were conducted to elicit the views of adults with Down syndrome and their support people about what factors facilitate physical activity and what factors are barriers to activity. A sample of 18 participants (3 men, 15 women) was recruited through two agencies providing services for adults with disabilities; six participants were adults with Down syndrome and 12 participants were support people (four were parents of adults with Down syndrome and eight participants were employed by day programmes attended by the adults with Down syndrome). The interviews were recorded, transcribed verbatim and independently coded by two researchers. Results Three themes around facilitators to physical activity were identified: (1) support from others; (2) that the physical activity was fun or had an interesting purpose; and (3) routine and familiarity. Three themes around barriers were also identified: (1) lack of support; (2) not wanting to engage in physical activity; and (3) medical and physiological factors. Conclusions The results suggest that support people play a key role, both as facilitators and barriers, in the participation by adults with Down syndrome in physical activity. Many of the barriers and facilitators of activity for adults with Down syndrome indentified are similar to those reported for adults without impairment. Our findings are also consistent with established theories in the field of health behaviour change. [source]


Preschool children with and without developmental delay: behaviour problems, parents' optimism and well-being

JOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 8 2005
B. L. Baker
Abstract Background Children with intellectual disability are at heightened risk for behaviour problems, and these are known to increase parenting stress. This study explored the relation of behaviour problems to less child-related domains of parent well-being (depression and marital adjustment), as well as the moderating effect of a personality trait, dispositional optimism. Method Participating children (N = 214) were classified as developmentally delayed, borderline, or nondelayed. Mothers' and fathers' well-being and child behaviour problems were assessed at child ages 3 and 4 years. Results Parents of delayed and nondelayed preschoolers generally did not differ on depression or marital adjustment, but child behaviour problems were strongly related to scores on both measures. Optimism moderated this relationship, primarily for mothers. When child behaviour problems were high, mothers who were less optimistic reported lower scores on measures of well-being than did mothers who were more optimistic. Conclusions Interventions for parents that aim to enhance both parenting skills and psycholog- ical well-being should be available in preschool. It may be beneficial for such programmes to focus not only on behaviour management strategies aimed at child behaviour change, but also on parents' belief systems, with the aim of increasing dispositional optimism.

An exploration of nutritional knowledge in a sample of Scottish men of low socio-economic status

NUTRITION BULLETIN, Issue 4 2000
Kerri E. McPherson
Summary The government has used health promotion campaigns as a means of improving nutritional knowledge in the Scottish population, in an attempt to encourage healthier eating practices and reduce diet-related illness. However, mismeasurement of nutritional knowledge and the presence of barriers to behaviour change, such as socio-economic status, means that the relationship between nutritional knowledge and dietary practice is not a straightforward one. The main findings of the present study are twofold. Firstly, the results emphasise the multidimensionality of the nutritional knowledge construct. Secondly, the results show that educational status is a major facilitator/barrier in the nutritional knowledge,dietary practice relationship. [source]


An interim analysis of a cohort study on the preoperative anxiety and postoperative behavioural changes in children having repeat anaesthetics

PEDIATRIC ANESTHESIA, Issue 9 2002
A. Watson
Introduction Anxiety in the preoperative period and at induction of anaesthesia in children is associated with disturbances in postoperative behaviour (1,4). There is little work looking at the effects of repeat anaesthetic procedures on anxiety and subsequent postoperative behaviour disturbances. The aim of this study was to see if the effect of repeat anaesthetics was cumulative on postoperative behavioural problems and whether repeated anaesthetics provoke increasing anxiety. We investigated factors that may identify children who are susceptible to behavioural changes following repeat anaesthetics. We present an interim analysis of data on 8 patients as part of a long-term cohort study on 40 children with retinoblastoma who have required repeat anaesthetics for assessment and treatment of their condition. Method Approval for this study was granted by the East London and City Health Authority ethics committee. 40 patients are being recruited and being followed over a two year period. All children have retinoblastoma and are between the ages of 18 months to 4 years. The anaesthetic technique was not standardised but details of it were collected. Data collected were demographic details of child (age, sex, weight, ASA grade, siblings, stressful events in the last 3 months, recent immunisations, number of previous anaesthetics, problems with previous general anaesthetics, medical history of children, temperament of child using the EASI scoring system (4); demographic data of parents (age, parental education, family members affected, baseline measure of parental anxiety using State trait anxiety inventory (STAI). Anxiety on entry into the anaesthetic room and at induction was measured by the modified Yale preoperative anxiety scale (mYPAS), cooperation of the child at induction was measured by the Induction compliance checklist (ICC). Anxiety of the parent after induction was measured by the STAI score. Behaviour was measured at 1 day, 1 week, 1 month and 4 months after each procedure by means of the post hospital behaviour score (PHBQ) (5). A comparison with preoperative behaviour was made and data is presented of the percentage of children with new negative behavioural problems. A detailed analysis of the types of behaviour change was noted. anova for repeat measures with multiple dependent measures was used to analyse data on child anxiety and postoperative behavioural problems. Results Eight patients have had 3 separate anaesthetics over one and a half years. These have been at 4 monthly intervals. There was no significant increase in anxiety levels with repeat anaesthetics. The median mYPAS score at induction were 100 for all 3 anaesthetics. (P = 0.41). The type of behavioural change was variable and demonstrated no trend. No patient was identified as being prone to behavioural changes after every anaesthetic. Patients who displayed new negative behavioural problems would have them after any anaesthetic with no obvious cumulative effect with each repeat anaesthetic. Conclusions Our patients had maximum anxiety scores at induction, so the mYPAS scoring system is not sensitive enough to show that repeat anaesthetics provoke increasing anxiety. There is a very random pattern to behavioural disturbances after repeat anaesthetics with no evidence that negative behavioural changes are compounded with repeated anaesthetics. Collection of complete data from the remaining 32 patients may yield some trends regarding behavioural disturbances but our use of the mYPAS to measure anxiety in this very anxious population is unlikely to be helpful.

Chinese medicine Banxia-houpu decoction regulates c-fos expression in the brain regions in chronic mild stress model in rats

PHYTOTHERAPY RESEARCH, Issue 3 2004
Weiyun Zhang
Abstract Banxia-houpu decoction is a safe and effective traditional Chinese medicinal formula used in the treatment of mild and manic-depressive disorders for centuries. There has been increasing interest in its therapeutic application in depression. However, the mechanisms behind behavioural changes are still poorly understood. Chronic mild stress (CMS)-induced preference behaviour change has been used as a model to predict the clinical ef,cacy of many types of antidepressant treatment. Both EtOH and water extracts (AE and WE) of Banxia-houpu decoction exhibited a signi,cantly increased sucrose intake in the CMS model in rats, but there was no effect in unstressed animals. In the present study, it was found that the c-fos expression in cerebral cortex, hippocampus and striatum corpora were very high in the CMS model in rats. WE and AE at a dose of 130 mg/kg exhibited a signi,cantly decreased c-fos expression in the cerebral regions in CMS model in rats, respectively. The former was more potent than the latter. However, no signi,cant changes in the c-fos expression were observed in unstressed rats treated with the decoction. Fluoxetine not only signi,cantly reduced c-fos expression in all regions in the CMS model in rats, but only showed a marked decrease in c-fos expression in the hippocampus in unstressed animals. A different molecular mechanism of Banxia-houpu decoction and ,uoxetine may be implied. The cerebral cortex, hippocampus and striatum conpora might be important structural substrates in the central nervous system mediating the section of the Banxia-houpu decoction on preference behaviour in CMS-induced rats, and fos protein might be the common substrate of the signal transduction process of the decoction.

Making People More Responsible: The Blair Governments' Programme for Changing Citizens' Behaviour

POLITICAL STUDIES, Issue 3 2010
Perri
A distinctive feature of the three Blair New Labour governments' domestic policy was the effort to change citizens' behaviour. Variously explained using such slogans as ,something for something', ,responsibility' and, in combating antisocial behaviour, ,respect', behaviour change was presented by the PM's Strategy Unit as an overarching strategic framework for policy. This included conditionality in welfare to work, health promotion campaigns, a ban on smoking in public places, measures to combat antisocial behaviour and enforce school discipline, home,school contracts, community cohesion and neighbourhood renewal programmes, measures to encourage car sharing and use of public transport, and others to promote domestic waste recycling. This article examines how far the two principal explanatory theories available predict that programme's characteristics. It uses a structured data set on the policy instruments, target groups and content of initiatives undertaken by eight central government spending departments. We find that indeed the strong (more coercive) tools are markedly concentrated on initiatives targeting the poor and low-income working strata. The expectations derived from the two theoretical traditions are not strongly supported. [source]


The power of policy to influence behaviour change: daylight saving and its effect on physical activity

AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2010
Michael Rosenberg
Abstract Objective: To measure the impact of the introduction of daylight saving in Western Australia in December 2006 on when during the day adults engaged in physical activity. Methods: In early December 2006, 1,300 Western Australian adults were telephoned and asked about how the introduction of daylight saving would influence when during the day they typically engaged in physical activity. At the end of the daylight saving period in March 2007, 1,083 of the baseline cohort agreed to answer questions relating to how daylight saving had affected when during the day they were physically active. Results: Almost half the cohort (45.5%) reported that daylight saving had affected when during the day they were physically active. During daylight saving fewer people exercised in the morning and more people exercised in the evening. When analysed at the individual level, 23% of the cohort ceased to exercise in the morning during daylight saving and 22% exercised in the evening only during daylight saving. In addition, to changes in when during the day people exercised, there was also an overall reduction in the average number of daily exercise sessions, with 8% not exercising at all during daylight saving. Conclusions: The results suggest that the introduction of daylight saving, a relatively modest compulsory change to increase daylight by one hour had an impact on patterns of when during the day people were physically active. Implications: The study results reinforce the value of focusing on policy as an effective means of supporting population behaviour change. [source]


Treatment fidelity as a predictor of behaviour change in parents attending group-based parent training

CHILD: CARE, HEALTH AND DEVELOPMENT, Issue 5 2009
C. Eames
Abstract Background Change in parenting skills, particularly increased positive parenting, has been identified as the key component of successful evidence-based parent training (PT), playing a causal role in subsequent child behaviour change for both prevention and treatment of Conduct Disorder. The amount of change in parenting skills observed after PT varies and may be accounted for by both the content of the programme and by the level of PT implementer process skills. Such variation in implementer skills is an important component in the assessment of treatment fidelity, itself an essential factor in successful intervention outcome. Aims To establish whether the Leader Observation Tool, a reliable and valid process skills fidelity measure, can predict change in parenting skills after attendance on the Incredible Years PT programme. Results Positive leader skills categories of the Leader Observation Tool significantly predicted change in both parent-reported and independently observed parenting skills behaviour, which in turn, predicted change in child behaviour outcome. Conclusions Delivering an intervention with a high level of treatment fidelity not only preserves the behaviour change mechanisms of the intervention, but can also predict parental behaviour change, which itself predicts child behaviour change as a result of treatment.

Therapist features in sexual offender treatment: their reliable identification and influence on behaviour change

CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 6 2002
W. L. Marshall
In the first of the two studies reported here, we established that trained judges could reliably identify 18 therapist features that occurred with reasonable frequency. In the second study 17 of these features were examined to determine how well they related to changes in sexual offenders with treatment. Five videotapes from each of five different prison programs were rated for the presence of these 17 features and correlational analyses examined their relationship with changes in 44 measures of treatment targets. The primary findings indicated that empathy and warmth displayed by the therapists and their directive and rewarding behaviours, were the features that most strongly predicted therapeutic benefits. The results are discussed in terms of their clinical and research implications. Copyright © 2002 John Wiley & Sons, Ltd. [source]


Sabotaging behaviour and minimal latex of Asclepias curassavica incur no cost for larvae of the southern monarch butterfly Danaus erippus

ECOLOGICAL ENTOMOLOGY, Issue 4 2010
DANIELA RODRIGUES
1. The southern monarch, Danaus erippus, uses mainly Asclepias curassavica as its host in the Neotropics, a plant species bearing articulated anastomosing laticifers. When artificially severed, A. curassavica has been shown to release significantly less latex than other Asclepias species. 2. The present study tested the hypothesis that sabotaging behaviour changes during the ontogeny of D. erippus and recorded latex outflow of A. curassavica during sabotaging and feeding. Larvae displayed vein-cutting behaviour, which was initially observed in the second instar, became more pronounced in the third and fourth instars, and less frequent in the fifth instar. When present, latex outflow was never more than 1 µl at a time during either vein cutting or feeding, regardless of the instar. 3. Mandibular and midrib morphometrics revealed that larvae selected thicker midrib sites for severing as instars progressed; however, no correlation between mandibular size and midrib size severed was found within instars. 4. Costs of sabotaging behaviour and the effects of A. curassavica latex outflow on D. erippus larvae were also examined. Sabotaging behaviour did not incur growth costs for larvae, and only latex exudation volumes at least 10-fold greater than those observed due to D. erippus sabotaging or feeding, caused significantly higher larval mortality than controls. 5. Since latex outflow is minimal or non-existent in A. curassavica, sabotaging behaviour in D. erippus is mostly limited by morphological constraints and is probably driven by chemical stimulants rather than latex defence. In turn, latex does not constitute a major defence of A. curassavica against D. erippus. [source]


Does the medial orbitofrontal cortex have a role in social valuation?

EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 12 2010
M. P. Noonan
Abstract It has been claimed that social behaviour changes after lesions of the ventromedial prefrontal cortex (vmPFC). However, lesions in humans are rarely restricted to a well defined cortical area. Although vmPFC lesions usually include medial orbitofrontal cortex (mOFC), they typically also affect subgenual and/or perigenual anterior cingulate cortex. The purpose of the current study is to investigate the role of mOFC in social valuation and decision-making. We tested four macaque monkeys prior to and after focal lesions of mOFC. Comparison of the animals' pre- and postoperative performance revealed that, unlike lesions of anterior cingulate gyrus (ACCg), lesions of mOFC did not induce alterations in social valuation. MOFC lesions did, however, induce mild impairments in a probabilistic two-choice decision task, which were not seen after ACCg lesions. In summary, the double dissociation between the patterns of impairment suggest that vmPFC involvement in both decision-making and social valuation may be mediated by distinct subregions centred on mOFC and ACCg respectively.

The Adaptive Brain: Glenn Hatton and the Supraoptic Nucleus

JOURNAL OF NEUROENDOCRINOLOGY, Issue 5 2010
G. Leng
In December 2009, Glenn Hatton died, and neuroendocrinology lost a pioneer who had done much to forge our present understanding of the hypothalamus and whose productivity had not faded with the passing years. Glenn, an expert in both functional morphology and electrophysiology, was driven by a will to understand the significance of his observations in the context of the living, behaving organism. He also had the wit to generate bold and challenging hypotheses, the wherewithal to expose them to critical and elegant experimental testing, and a way with words that gave his papers and lectures clarity and eloquence. The hypothalamo-neurohypophysial system offered a host of opportunities for understanding how physiological functions are fulfilled by the electrical activity of neurones, how neuronal behaviour changes with changing physiological states, and how morphological changes contribute to the physiological response. In the vision that Glenn developed over 35 years, the neuroendocrine brain is as dynamic in structure as it is adaptable in function. Its adaptability is reflected not only by mere synaptic plasticity, but also by changes in neuronal morphology and in the morphology of the glial cells. Astrocytes, in Glenn's view, were intimate partners of the neurones, partners with an essential role in adaptation to changing physiological demands. [source]
